Step 1
Butter four 6-ounce ramekins and place remaining butter in a medium mixing bowl; set aside.

Step 3
Add remaining 3 tablespoons flour, 2 tablespoons sugar, and 1/4 teaspoon salt to the butter in the mixing bowl Add oats and cinnamon. Cut dry ingredients into the butter with a fork until crumbs are pea-sized. Stir in walnuts. Divide topping evenly among the ramekins.
